Abstract

An indirect measurement of the temperature of a molten bath (1) of a viscous material such as glass is made by measuring a parameter such as the motor torque of a rotating mechanical stirrer (3) or the calorific power extracted from its cooling water. This dispenses with a direct measurement of the temperature by a probe tube fitted with a thermocouple and exposed to difficult operating conditions.

Description

The measurement of molten glass bath temperature
Technical field
Theme of the present invention is melten glass liquid-bath or the very measurement of the temperature of sticking material that remains on comparatively high temps.
Background technology
This temperature survey is essential in monitoring the vitrifying process, yet because the temperature that molten glass reaches is very high, it is difficult that measurement will become.The intensity that major part is used to make the conventional material fusing of transmitter or loses them at least.Another kind of technology measures on the refrigerative bar temperature that is lower than the actual temperature that reaches of glass by temperature sensor being arranged on by current.Solidifying the glass slag is formed on around the bar and guard bar avoids overheated and is corroded.By related function, the temperature of molten glass bath can be derived from observed temperature and be drawn.But this measuring technology by cooling rod has been proved to be feasible inaccurate, reason is: it is relevant with the single position of glass bath, and this position temperature of liquid-bath may be uneven, and this technology is very responsive to the physical condition of liquid-bath, and significantly be subjected to the influence of nature or forced convection campaign, and also be subjected to covering the influence of its variable thickness that solidifies glass thus.
Summary of the invention
These shortcomings cause having produced according to improvement measuring method of the present invention, in the method for the invention, thus the method for directly measuring actual temperature or reduced temperature use by having the measurement of another parameter that function gets in touch to replace finishing the indirect measurement of latter's temperature with temperature.Here imagining the general character of parameter, is that they and liquid-bath are uncorrelated, therefore do not need transmitter is arranged in the crucible that comprises liquid-bath but outside, transmitter moves in heat-eliminating medium under better condition like this.
The present invention is based on a kind of special applications of the mechanical stirrer of molten glass bath.Known agitator has multiple shape, and generally include rotator with blade or similarly device be used for moving glass and stirring around their.This agitator keeps the temperature of appropriateness by its loop of cooling fluid of flowing through in concentric pipe or other device.
With can obtaining by the operation agitator of the temperature correlation of liquid-bath to measuring useful parameter.It should be noted that cooling further can produce some and solidify the glass slag around agitator, but by make around the blade and the agitator central shaft near the thickness of the glass that solidifies stable, and the stirring of situation of liquid-bath around the adjusting vane, this under the situation of measuring temperature with bar disadvantageous situation no longer occur at this.Because agitator directly contacts the liquid-bath of largest portion further, so the heat of its acceptance can reflect the bulk temperature or the medial temperature of liquid-bath better.
In a specific embodiment about the inventive method, the heat energy of parameter to be measured for from the cooling fluid of the agitator of flowing through, drawing of expression liquid-bath temperature.In another specific embodiment, treat that measured value is under a steady speed, the motor torque of agitator.
The present invention is described by the help of accompanying drawing 1 now, and it has shown the liquid-bath that belt stirrer is provided.Accompanying drawing 2 has shown cooling loop.Accompanying drawing 3 has shown an example.Liquid-bath is a label 1, and it is positioned at the crucible 2 (such a situation is very common, comprises near the independent telefault that is positioned at crucible 2) that has unshowned heating unit.No matter be in the power supplier commonly used of crucible or the prior art extensively known to and have nothing to do and all be not shown in the casting valve in downstream of the present invention.Crucible 2 comprises the agitator 3 of anchor shape, at this and comprise plunger axis 4 and a pair of reverse blade 5.Axle 4 is supported by bearing (bearing) 6 and is driven rotation by the motor 7 of being furnished with speed reduction unit and torque variator.Agitator 3 be hollow and comprise pipe core 8 so that will be used to inject the peripheral channel 9 of cooling fluid internally and separate with the former concentric centre channel 10, the water of injecting can reclaim once more.Manage 8 branches and enter each blade, its end end is that open being used to allows water to flow into centre channel 10 from peripheral channel 9, this loop further comprises the pipeline 13 of the water tank 11, pump 12, connection pump 12 and the water tank 11 that are placed on axle 4 tops, and comprises the cooling apparatus 14 on suction tube, delivery pipe and the pipeline 13.
The present invention also can be by the agitator of other mixer operations, particularly spiral or coiled type.It also is suitable regularly cooling off whole agitator surface fully.In addition, blade 5 has whole mixing that sufficient extension is used to finish liquid-bath.But it should be noted that this liquid-bath is equipped with other agitators if what be applied to liquid-bath is small-sized agitator, do not carry out measurement on these agitators and but share the former mixing functions that invention also can be carried out suitably.
In a specific embodiment about the inventive method, measure the heat energy that absorbs by agitator 3, its can be according to the flow velocity of pump and the temperature deduction that is positioned at the water coolant that the transmitter 15 and 16 of peripheral channel 9 inlets and centre channel 10 outlets records draw.Being used for thermometric application of formula is: T 1 = C 1 ln ( C 2 P ) , T herein 1Be the temperature of finding the solution, C 1And C 2Be the experience constant that is obtained by before experiment, P is a heat energy.Liquid-bath volume and liquid-bath composition that constant in fact only depends on the rotating speed of agitator and determines device.
In another embodiment of the present invention, the motor torque of agitator is used to finish the indirect measurement of liquid-bath temperature.This measurement even can be simpler can realize by the torque measurement device 17 that is arranged on the transmission mechanism between motor 7 and the axle 3.At this moment relevant formula becomes T 2 = C 3 ln ( C 4 C ) , T herein 2For the temperature of liquid-bath (should with T 1Equate), C 3And C 4Be the other constant that is obtained by before experiment, C is the torque that records.Here constant C 3And C 4For fixed device is constant, only depends on the volume of rotating speed and melting material.
These two kinds of measuring methods can be used separately or together.
Accompanying drawing 3 provides an embodiment, and by using first formula, wherein coefficient is C 1=-108.7 and C 2=0.0091, the power P of agitator is represented by watt, temperature T 1Represent by centigradetemperature.This process comprises a series of circulations, it little by little pours into crucible for the fixing glass of forming, according to the indication of reflection, after fusion, promptly remove then with respect to the curve 18 of weight of glass in time (X-coordinate be hour) crucible (the right ordinate zou scale for kilogram).Parameters C 1And C 2Estimatedly in circulation before go out.
Provide the actual temperature curve 19 that records by thermopair of liquid-bath, and those temperature curves 20 of (left side ordinate zou scale) estimation according to the present invention.The shape of these curves is very consistent, and curve 20 only contains fluctuation, and this curve of cyclical fluctuations presents the envelope curve at about 20 degrees centigrade of intervals under the quasi-steady state recurrent state, and curve 20 comprises curve 19.
